COIN-OPERATED LOCK.

l Appiicanon filed september 2z, 1,927.l sensi No. 221,331.

Our invention relates to improvements in coin operated locks. s

The object of our invention is to provide a `coin operated lock asV controlling means for reserved seats. l

i A `further object of our invention is to provide a coin operated lock that may be adjusted for coins of different size and.

value. v l ,p

These and other objects will be hereinafter more fully explained, reference being had to the accompanying drawings 'forming a f partlofthis specification in which:

Fig. 1 is an elevation 'partly in Lsection for convenience of illustration. 1

Fig. 2 is a transverse view partly in section.

Fig. 3 is a detailed side view of the-knob and shaft on which theicoin receiving member is mounted, a portion of the shaft removed to show the key way. y

Fig. l is a sectional view of the coin y ing means.

Fig. 5 is a plan v iew'of the coin slot. Fig. 6 is a sectional view through Fig. 5

taken on line 6 6.

Fig. 7 is a perspective View of a seat ledge, showing the reserved seats positioned thereon l . consists of a housingl having a lid 2'positioned on Vthe inside thereof. Rotatably mounted in the .housing is a' shaft 3, having a knob 4, and may be integral therewith.,

Y hs means to secure the shaft from longitudinal movement, we have placeda collar thereon, the said vcollarbeing secured by a set screw 6; the knob fl has a hub v7 to engage on the outside of the housing as.

spacing means for the knob from said housing, the housing` positioned between-the end y of the hub and the collar, the opposite end of the shaft rotatably engages in an aperture in the lid 2. Removably attached to the shaft and rotatable therewith is a vcoin receiving member 8, said member having a.vv plurality of notches 9 radially positionedand functioning as coin pockets.

Y. Fig. Sis a front view of one ofthe seats,

)utwardly` enrtendingy from the coin receiving member are pins 10 that are positioned between the notches functioning as a ratchet and meansto properly position the notches in vertical alignment with the coin slot hereinafter described.

Rockably mounted in the housing is a pawl 11 thatis tensioned by a leaf spring 12, the

v said p'awl is provided withv a seat 13 adapted spout 15 as guiding means for the coin as itcontacts with a pivotally mounted bar 16, said bar being vertically positioned and tensionediby a spring 17 on the upper end of the bar is a hook' 18, adapted to engage with a hook 19, the last said hook being firmly l attached to a lid 20, functioning as an enclosure for. a; seat, as shownin Fig. i' the lirst said bar has reverse curves so that the coin will Contact on curve Apthrowinglihe bar outward asshown by `dotted lines B, as disengaging means for the hooks.

Between the lid and seat inclosure 22 are springs 28 as Vnieans to raise the lid slightly,V preventing rc-engagement of the lock until the lid is opened as shown in Fig. 7.

y vTo prevent the exposure of said' springs, we have positioned dowels ,2li .in the, lid, thc

said dowels adapted to enter the spring aperture, by which means when the lid is opened the top of the springs will not pass from their respectivev apertures. l Y Vhen the ,lockl is disengaged, a pin 16 functions as astop for said b'arag'ainst the Y tension of its respect-ive spring. p

When the mechanism isto be operated by coins of differentv diameter, a rcoin receiving member .is provided having notches con forming to the size of the" coin; by such arrangement the peripheral edge of the coin will travel inthe sameV arc at alltilncs in the rotation of the coin receiving member,

the object ofy which will be to maintain the contact and action required to operate the lock bar 16 will' be thepsame. v

As means to yremove and replace the coin lil receiving member, we have provided a key way in the shaft 3 and a key 26 rigidly attached in the aperture of the coin receiving member which is adapted to slidably engage in said key way.

Between said coin receiving member and the lid 2 is a coil spring 27 as tensioning means to snugly position said member against the collar 5, and in registry with the spout.

It will be understood that when the coin receiving members are to be changed, the set screw in collar 5 will be removed, at wliichtiine the shaitt is free to move longitudinallyY until disengaged 'from the aperture ot said member, which may then be removed and replaced by another, the shaft being retracted to its normal position and the collar rigidly attached renders the mechanism in condition for Jiurther operation.

ln the lid of the reserved seat adjacent the lock is positioned a slot in radial alignment with the coin receiving member, so that the coins entered therein will drop in the notch of the coin receiving member, which at all times is in registry with the slot, and by rotating the said member clock-wise through the medium of the knob 4l the coin deposited there-in is carried to engagement with the locking bar, 'forcing it outward and locking y the lid, as heretofore described.. After the lock is disengaged, the coin is free to drop downward into a coin receiving chamber provided for this purpose beneath the seat.

W hen diifcrent sized coins are to be used, a member 28 is provided with a slot to conform to the size ot the coin and is interchangeable, seating within a plate 29 and rigidly attached by means of screws 30.

While lj have shown the coin operated lock in connection with reserved seats, I do not confine it to this purpose alone, and such modifications may be employed as lie within the scope oli' the appended claims.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is:

l.v ln a coin operated lock, a housing and a notched coin receiving member rotatably mounted therein, an interchangeable slot and a spout as conveying means tor the coins into the notches of the coin receiving member consecutively, pins outwardly extending from the sides ot' said member and positioned relative to the notches, a spring tensioned pawl having a seat and an extension to en! gage ywith two adjacent pins as positioning means for the notches in registry with the slot and spout, a spring tensioned bar pivotally attached at one end, a hook on the other end to engage with a similar hook member attached to a lid as locking means tor the lid, a curvature in the bar as a contact point for the peripheral edge of a coin rotated to engagement therewith by said coin receiving member and means to rotate said member.

2. In a coin operated lock, the combination of a housing, ot a bar having a hook on one end, the other end pivotally connected to the housing, a spring tensioning means for the bar and a stop for the tree end, of a spout hafing an interchangeable slot on the outer end thereof attached to the hous ing, of a member having a plurality of slots or pockets spaced peripherally thereon, a spring tensioned means and pins laterally extending from the side of said member to engage with said means to accurately position and detain the notches in vertical alignment with the slot consecutively to receive a coin as dropped through a slot, the coin` functioning as outward rocking means for the spring tensioned bar, and conveying means tor the coin when released from the notch.

3. ln a coin operated lock, a coin manipue lating means of the kind described, compris ing a housing, a rockably mounted bar having a hook as attaching means to a hook of a lid or the like, a shat't having a knob as rotating means therefor, a` collar on vthe' shat and means to rigidly attach thereto, as securing means for theshaft in its bearings in the housing, a notchedcoin receiving member, loosely keyed to the shaft and rotatabletherewith, a'spring coiled about the shaft as tensioning means tor said member against the collar, a spout having a segmental curvature with sides between which the coin receiving member engages, the segmental portion of the spout to function as guiding means for the coin as carried to engagement with the said bar, a spring tensioned pawl to prevent anticlockwise movement of the coin receiving member, and as a stop in registry with the notches with the vertical portion of the spout consecutively as said member is rotated, all as and for the pur pose described.

ln testimony whereof we afiX our signatures.
